An experiment was conducted to study the effect of fertigation levels and schedules on growth, yield and nutrient uptake of tomato under polyhouse. The treatments included 3 fertigation levels (F1- 60% of RDF, F2- 80% of RDF, and F3- 100% of RDF) and 3 fertigation schedules (S1-6 equal splits of RD of NPK at every 18 days interval, S2-9 equal splits of RD of NPK at every 12 days interval, S3-12 equal splits of RD of NPK at every 9 days interval). The results indicated that fertigation of 100 per cent RD of NPK (300:150:150 N, P2O5, K2O kg/ha) in 12 equal splits at every 9 days interval up to 120 DAT was found significantly superior in case of growth, yield attributes and fruit yield of tomato. However, it was at par with 80 per cent RD of NPK (240:120:120 N, P2O5, K2O kg/ha) in 12 equal splits at every 9 days interval up to 120 DAT. Similarly, significantly maximum nitrogen, phosphorus and potassium uptake by tomato plant was registered with fertigation of 100 per cent of RDF and 12 equal splits of NPK at every 9 days interval up to 120 DAT. It was further concluded from the study that fertigation of 80 per cent RD of NPK (240:120:120 N, P2O5, K2O kg/ha) in 12 equal splits at every 9 days interval upto 120 DAT was found to beneficial for higher growth and fruit yield of tomato under polyhouse condition during summer season.Keywords

The treatment combination S3I1F1 [planting geometry S3 175 - 50 x 50 cm with irrigation level I1 100% ETcrop and fertigation level F1-100% RDF through drip (WSF)] recorded higher values of fruit yield (49.8 t ha-1), highest grosss income (Rs. 4,48,420 ha-1) and maximum B:C ratio (2.61) over the rest of treatment combinations. The lowest values of fruit yield (27.4 t ha-1), gross income (Rs. 2,46,360 ha-1) and B:C ratio (1.31) was noticed under treatment combination of S1I3F2 of plant spacing 75x75cm with irrigation level 60 per cent ETcrop and fertigation level 80 per cent RDF through drip (WSF). While the control C2 (surface irrigation with 1.0 IW/CPE ratio) showed lowest average values of fruit yield (12.8 t ha-1), gross income (Rs. 1,15,310 ha-1) and B:C ratio (1.04).Keywords

A field experiment was conducted during Kharif seasons of 2012, at Mahatma Phule Krishi Vidyapeeth, Rahuri, dist. Ahmednagar to study effect of foliar sprays of water soluble fertilizer, growth regulator and micronutrients on yield and quality of soybean. Significantly higher grain yield (22.70 q ha-1) and straw yield (21.00 q ha-1) was obtained in treatment GRDF + foliar spray of 19:19:19 NPK 0.5 % + H3BO3 0.5 % + ZnSO4 0.5 % at 30 and 40 DAS. Among the treatment highest protein content (38.54%) and oil content (19.14%) was obtained in treatment GRDF + foliar spray of 19:19:19 NPK 0.5 % + H3BO3 0.5 % + ZnSO4 0.5 % at 30 and 40 DAS.Keywords
